City Under One Roof by Iris Yamashita

A stranded detective tries to solve a murder in a tiny Alaskan town where everyone lives in a single high-rise building, in this gripping debut by an Academy Award–nominated screenwriter.

When a local teenager discovers a severed hand and foot washed up on the shore of the small town of Point Mettier, Alaska, Cara Kennedy is on the case. A detective from Anchorage, she has her own motives for investigating the possible murder in this isolated place, which can be accessed only by a tunnel.

After a blizzard causes the tunnel to close indefinitely, Cara is stuck among the odd and suspicious residents of the town—all 205 of whom live in the same high-rise building and are as icy as the weather. Cara teams up with Point Mettier police officer Joe Barkowski, but before long the investigation is upended by fearsome gang members from a nearby native village.

Haunted by her past, Cara soon discovers that everyone in this town has something to hide. Will she be able to unravel their secrets before she unravels?"
